Patented Mar. 6, 1934 UNITED ST TES PATENT OFFICE This invention relatesto a slide caster for furniture, and it is an object of the invention toprovide a device of this kind especially adapted for use in connectionwith furniture placed upon hardwood or highly polished floors.

It is also an object of the invention to provide a device of this kindconstructed in a manner whereby the contacting surface of the castercomprises a plurality of fibrous strands which provide a contact withthe floor without marring or otherwise injuring the surface and whereinsuch fibrous covering is treated with wax or a kindred substance toassure a further desirable contact of the caster with the fioor surface.

Another object of the invention is to provide a device of this kindcomprising a core or base member around which a cord or strand offibrous material is wound to provide a contacting surface unharmful tothe door surface and wherein the wrapping of the fibrous cord'or strandis such to provide a central pocket to compensate for any gritty matterwhich may be upon the floor surface.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved slidecaster whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanying drawing,wherein:

Figure 1 is a view in top plan of the core or base member as comprisedin my improved caster;

Figure 2 is a transverse sectional view taken through the core or basemember as illustrated in Figure 1;

Figure 3 is a view similar to Figure 1 showing the core or base memberpartially wrapped;

Figure 4 is a View similar to Figure 1 showing the core or base membercompletely wrapped;

Figure 5 is a view in side elevation of the complete device asillustrated in Figure l with an applied protecting cap shown in section;

Figure 6 is a fragmentary sectional view taken through the flangeportion of the protecting cap as herein employed;

Figure 7 is a fragmentary view in bottom plan of the caster as hereindisclosed.

As disclosed in the accompanying drawing, my

improved caster comprises a basemember B having a circular plate 1 ofsheet metal having a centrally arranged tang 2 struck therefrom andarranged at right angles thereto as illustrated in Figure 2. This tang 2is preferably substantially triangular in form as is clearly indicatedby the resultant opening 3 in the plate 1 after the tang 2 has beenstruck.

The periphery of the plate 1 is provided therearound with a series ofoutstanding radial fingers v 4 having their extremities angularlydisposed, as

at 4, in the same general direction as the tang 2. The portions betweenthe inner ends of the fingers 4 provide notches 5 in which are engagedcords or kindred strands 6 of fibrous material wrapped around the coreor base member B. The wrappings around the core or base member 13 are ofany desired number and are disposed chordal of .the core or base memberB as particularly illustrated in Figure 4 resulting in the outer orworking face of the completed caster being provided with a centralpocket 7 which readily compensates for grit which may be encounteredupon the floor or other surface over which the caster may he slid. Inother words, the pocket 7 provides a chamber to receive such grit or thelike which might otherwise have a tendency to scratch the floor surface.

As the strands are wrapped around the base or core member B they arereceived within the notches or recesses 5 and as the wrapping iscompleted the extremity of each of the cords or strands is engaged.between an angular portion 4' of a finger 4 and the matted strandsarranged inwardly of but immediately adjacent to the portions 4 of thefingers and around the peripheral portion of the inner face of the coreor base member B.

- The cords or strands 6 are preferably treated with wax or kindredmaterial so that the desired contact of the slide caster upon the flooror a polished surface is rendered more desirable.

As particularly illustrated in Figures 5 and 6 a cap 8, preferably ofmetal, is provided defined by a resilient fiange 9 which is adapted tobe snapped or forced over the working or contacting face of the caster.This cap 8 is of especial advantage in protecting the fibrous laminationwhen the caster is applied to furniture in storage or placed on a roughsurface, such as concrete or the like, and at which time it is of coursedesired to protect the fibrous lamination.

From the foregoing description it is thought to be obvious that a slidecaster constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim:-

1. As a new article of manufacture, a slide caster for furniturecomprising a core, and a strand of fibrous material wrapped on the coreto provide a fibrous facing for the caster, said fibrous facing beingadapted for direct contact with the floor or other surface.

2. As a new article of manufacture, a slide caster for furniturecomprising a core, and a strand of fibrous material wrapped on the coreto provide a fibrous facing for the caster, said fibrous facing beingadapted for direct contact with the fioor or other surface,the peripheryof the core having notches therearound which receive the strand ofmaterial wrapped therearound.

3. As a new article of manufacture, a slide caster for furniturecomprising a core, and a strand of fibrous material wrapped on'the coreto provide a fibrous facing for the caster, said fibrous facing beingadapted for direct contact with the floor or other surface, said strandbeing wrapped over the outer face of the core in chordal relationthereto to provide the fibrous facing of the caster with a centralpocket.

4. As a new article of manufacture, a slide caster for furniturecomprising a core, and a strand of fibrous material wrapped on the coreto provide a fibrous facing for the caster, said fibrous facing beingadapted for direct contact with the floor or other surface, theperiphery of the core being provided therearound with a series of spacedfingers between which the strand is wrapped.

5. As a new article of manufacture, a slide caster for furniturecomprising a core, and a strand of fibrous material wrapped on the coreto provide a fibrous facing for the caster, said fibrous facing beingadapted for direct contact with the fioor or other surface, theperiphery of the core being provided therearound with a series of spacedfingers between which the strand is wrapped, the outer portions of thefingers being angularly disposed.
